Tower vs Similar Bookshelf?


I asked this question in an unrelated thread but did not get an answer so I'm going to see what kind of input I get by posting as a separate thread:

I'm looking at lower end speakers for my cabin.

I was looking at a certain brand and noticed their lowest end small tower speaker had a 6.5" woofer and 1" tweeter. These were the same woofer  and  tweeter that come in one of their bookshelf speakers. The towers cost about $100-$150 more than the bookshelf version. Both have bass ports in the the rear.

My question is: Is there any sonic benefit over the tower model verses the bookshelf model with essentially the same hardware? Better bass? Different crossover? Any thoughts appreciated.

Thank you. That makes sense. I was looking for bookshelf to keep the cost down but in truth, for this application, a tower would be easier to position. So with that and the advantage of better bass the $100 might be worth it.
I answered you a moment ago in your earlier thread, n80. The bookshelf really never keeps the cost down, because you have to add stands to get an equivalent sound. Or, put them on shelves, etc, and ignore the difference. It's not just better bass, either. Everything is improved, or usually so, when the drivers are up at a proper height and away from the walls (or books). :)
Not sure what speaker you are looking for but there is a set of new Klipsch RF 62 II on A’gon for $650 free shipping they have dual 6.5 woofers and at 97db will not take very many watts to get them loud not sure about SQ. 
Didn't see a $$ limit I thought $650 was pretty good for towers with dual 6.5 woofers.
